Eaton | FDB4045 | Circuit Breaker | 45A | 4-Pole | 600V

Eaton FDB4045 is a robust, four-pole circuit breaker engineered for demanding electrical distribution tasks. With a 45A rating and a 600V potential, this unit is purpose-built for maintenance, retrofit, and replacement projects where exact specifications are essential to keep systems safe and compliant.

• Amperage: 45A
• Poles: 4-Pole
• Voltage rating: 600V
• Best reference for compatibility: Part number FDB4045
• Ideal applications: maintenance, retrofit, and replacement requiring precise spec alignment

Why the 4-pole design matters

The 4-pole configuration provides simultaneous disconnection of all conductors in a 3-phase system, including neutral lines where required. This coordinated shutoff enhances safety during servicing and ensures a clean, predictable power isolation for connected equipment.

Ideal use cases

• Upgrading or refurbishing industrial panels that require a 45A, 600V 4-pole breaker
• Replacing a deteriorated or obsolete unit with a direct-spec part for reliable performance
• Retrofits in facilities where exact amperage, pole count, and voltage are non-negotiable

Compatibility and ordering tips

To ensure a precise fit, always verify the panel’s rating and mounting compatibility before ordering. The part number FDB4045 is the most reliable reference to confirm alignment with your equipment and wiring scheme.

Installation and practical considerations

When installing, ensure your system supports 600V circuits and that all conductors are de-energized prior to replacement. Align mounting and terminal connections with your panel’s specifications, and follow relevant electrical codes to maintain safety and compliance.

Designed for professionals managing industrial electrical protection, the Eaton FDB4045 delivers dependable performance for 3-phase distribution with clear, actionable compatibility guidance and a focus on safety during maintenance, retrofit, and replacement projects.
